Operating Instructions
1. Proper Cuff Placement
For accurate readings, proper cuff placement is crucial:
- Ensure your arm is bare or has only thin clothing.
- Place the cuff on your upper left arm, approximately 1-2 cm above the elbow joint. The artery mark on the cuff should align with your brachial artery.
- The bottom edge of the cuff should be about 1-2 cm above the elbow.
- Wrap the cuff snugly around your arm, ensuring it is not too tight or too loose. The hook-and-loop fastener should be secure.
- Sit comfortably with your back supported and feet flat on the floor. Rest your arm on a table so the cuff is at heart level.

2. Taking a Measurement
Press the START/STOP button to begin a measurement. The cuff will inflate automatically. Remain still and silent during the measurement process.
The Microlife Series 600 features Microlife Averaging Mode (MAM). When MAM mode is active (indicated by the MAM symbol on the display), the device will automatically take three consecutive measurements with a short pause in between. The final displayed result will be the average of these three measurements, providing a more reliable reading.
3. Understanding Your Readings
After the measurement is complete, the display will show your systolic pressure (SYS), diastolic pressure (DIA), and pulse rate (PULSE/min).
- Systolic Pressure (SYS): The pressure when your heart beats, pumping blood.
- Diastolic Pressure (DIA): The pressure when your heart rests between beats.
- Pulse Rate: Your heart rate, measured in beats per minute.
The monitor also includes a Hypertension Risk Indicator (color-coded bar on the left side of the display) and an Irregular Heartbeat Detector (IHB symbol). Consult your physician if you frequently observe high readings or the IHB symbol.

4. Memory Function and User Selection
The device stores up to 198 measurements (99 per user) with date and time stamps. To switch between User 1 and User 2, press the M button when the device is off. To view stored measurements, press the M button repeatedly after selecting the desired user.
